Description

In the function recv_parse_or_apply_log_rec_body() there are debug checks for validating the state of the page when redo log records are being applied. Most notably, FIL_PAGE_TYPE should be set before anything else is being written to the page.

The function ibuf_add_free_page() is violating this by invoking flst_add_last() before setting FIL_PAGE_TYPE. This bug was noticed during the testing of ~~MDEV-19514~~.
